The coastal domain of central western Sicily is characterized by the presence rocky coasts, which mainly consist pocket beaches situated between bedrock headlands that constitute ecological niches great touristic and economic value. In this peculiar morphodynamic system, sedimentary contributions are derived from rockfall affects back nearby cliffs or sediment supply small streams flow into it....

Key to the quantification of rockfall hazard is an understanding its magnitude-frequency behaviour. Remote sensing has allowed for accurate observation activity, with methods being developed digitally assembling monitored occurrences into a database. A prevalent challenge volume, whilst fully considering 3D information stored in each extracted point clouds. Surface reconstruction utilized const...

The migration process of rockfall has certain complexity and randomness in steeply dipping coal seams (SDCS). three-dimensional random with parameters cannot be accurately simulated. Taking the transport arbitrarily shaped formed by roof leakage steep seam working face as research object, a method for generating shape irregular polyhedrons based on ellipsoid equation is provided. And geographic...

Abstract The fragmentation phenomenon has a significant effect on rockfall risk assessment. This information is difficult to obtain, but it key improving modelling. For this reason, the RockModels team gathered data of several natural events since 2014 that nowadays wants share them with professionals, academics and stakeholders. best way for dissemination use standard or specifications in orde...
